The back story behind the creation of the Omega Speedmaster X-33 now deemed the "Skywalker" is fascinating. The watch came about as a collaboration between NASA, Russian astronauts, and former military pilots. The goal was to create the best possible watch to be used in outer space, which meant putting the Speedmaster through an array of rigorous tests. The watch is entirely cased in titanium, making it an incredibly light but sturdy watch. Ours is accompanied by its original box & papers.
